摘要：
An apparatus includes a moving mass transducer. The moving mass transducer generates sound by displacement of a surface defined by a piezoelectric element. The piezoelectric element is displaced in response to an interaction of a first signal with a magnetic field. The piezoelectric element is configured to be separately driving by a second signal.
